Oklahoma Sooners: Drayvon Henry

The Big 12 added several talented recruits on signing day with at least one member of the ESPN 300 inking with every Big 12 school except Kansas State. Several of those talented freshmen will get the opportunity to make an immediate impact this fall. Here are the top five impact freshman in the Big 12 in 2014:

Max Olson/ESPNK.D. Cannon has the skills to force his way into Baylor's receiver rotation as a freshman.

1. Allen Lazard, Iowa State receiver: The Cyclones are looking for playmakers on offense, and the No. 148 player in the ESPN 300 appears ready to fill that need. Lazard brings terrific size (6-foot-5, 208 pounds), strength and good hands to ISU’s offense. Quenton Bundrage needs help in the passing game and Lazard has the skills to join E.J. Bibbs in providing help in 2014.

“Allen is a guy who could come and make an impact,” Cyclones coach Paul Rhoads said. “We’re going to give him every opportunity to come in and play his way onto the field as a true freshman. This is a guy who is going to continue to challenge himself, day in and day out, for the rest of his career.”

2. Nigel Bethel, Texas Tech cornerback: The Red Raiders are losing several senior defensive backs including cornerbacks Bruce Jones, Derrick Mays and Olaoluwa Falemi. Yet Bethel could combine with 2013 signee Justis Nelson to give the Red Raiders one of the best cornerback duos in the Big 12 over the next few seasons. As one of the best cover cornerbacks in the Class of 2014, Bethel should see the field early. Bethel, the No. 226 player in the ESPN 300, has the speed, ball skills and natural instincts to make a smooth transition to college football.

3. K.D. Cannon, Baylor receiver: The Bears don’t have a major need at receiver but Cannon is an exceptional talent. Cannon, ranked No. 30 overall in the ESPN 300, needs to put on additional weight but he should be able to overcome his slight build thanks to his excellent feet and quickness.

“K.D.'s the smoothest and purest receiver at the high school level I've ever seen,” Baylor coach Art Briles said. “When the ball's in his hands, he is as instinctive as anybody I've ever been around.”

4. Steven Parker II, Oklahoma safety: The Sooners were the first team to offer the Jenks (Okla.) standout and remained in hot pursuit until he signed. Their pursuit could pay off as early as this fall. The No. 139 player in the ESPN300, Parker will bring athleticism and versatility to the Sooners secondary.

“He’s a guy we desperately needed at safety,” OU defensive coordinator Mike Stoops said. “Because he’s a guy that brings a different element to the safety position that a lot of players just can’t just by his mobility, his skill level, his cover ability. We ask our safeties to do a lot of that and he fits perfectly in to our system.”

5. Dalvin Warmack, Kansas State running back: Warmack should get plenty of opportunities to make an impact for the Wildcats. KSU is looking to replace John Hubert, who carried the load in the backfield for the past three seasons, rushing for 2,965 yards and 28 touchdowns.

With Jake Waters under center and Tyler Lockett making plays on the outside, KSU will need someone to help ensure offensive balance. Warmack can help keep defenses honest with his vision, versatility and open-field running. He might not be ready to step in and replace Hubert on an every-down basis but Warmack has the talent to make an immediate impact.
